This video will show the ways people use sound and light to communicate. A traffic light helps pedestrians and drivers on the streets and a lighthouse helps ships to navigate at night or in foggy weather. A doorbell tells us that someone is at the door and emergency services use sound to inform people that they are rushing for help. This video will also be helpful if children need to review the concepts of light and sound. It will remind them about different sources of light and sound, natural and man-made, as well as show what helps us to see and hear.
If you want to learn sound and light then you are at the right place as we will guide you through it all.
Sound:
The sound is a type of energy that is produced when something vibrates. For example, when you put on songs on the stereo speaker, it creates sound and you hear the music you want to.
Light:
Light is basically made up of waves that travel from different light sources. What actually happens is that light goes to the objects first and then it bounces off towards our eyes which is when we start seeing things.
These are the basics you will learn in science for kids and you can even look upon science for kids videos on the internet for more examples and explanations about how light and sound works.
In this video, students will explore what sound is and where it comes from. Children will learn that sound is a type of energy and everything that makes sound also uses energy. Children will also learn that sources of sound can be found in our houses, in the streets, around our towns and cities, and even in the sky.
From this video, children can learn more about the concept of sound. They will learn that sound is a type of energy and that it is caused by vibrations. These vibrations travel trough the air until they reach our ears, allowing us to hear. It would be interesting for children to find out that musical instruments use these vibrations to create beautiful sounds, or that harder objects vibrate better and produce a louder sound. The simple experiments shown in the video are very easy to recreate at home or in the classrom, which will help children to grasp the topic faster.
Sources of light is a very early lesson that kids need when they start understanding the concept of light. To help you explain this to your kid in easy words let me explain it to you in simple words.
What is light?
Light is what enables you to see around you. To put it in the words of science, light is made up of waves. And where do these waves come from? These waves travel from light sources, the bounce of different objects and enter our eyes, which then allows us to see things.
The kids can later understand the concept of waves in their higher grades.

How Light Travels Worksheet
With this colorful worksheet, your students can learn more about the way light travels. They will learn that light beams travel in a straight line, and cannot go around corners. Students will need to look through the pictures and check off all the correct examples of how light travels.
Ask your students if they know the different senses that we all have. Before starting this worksheet, make sure that your students know that we have the eyes for seeing, the tongue for tasting, the skin for feeling, the nose for smelling, and the ears for hearing. This worksheet will be showing your students more about how we hear sounds with our ears. They will read or listen to the text and examine the pictures carefully in order to answer the questions and check off the correct answers.
This worksheet is a fun and easy way to teach children about where light comes from, and what objects produce light. Children will need to identify natural light sources such as the sun and lightning, as well as man-made light sources such as candles and lamps. Ask your children to look at each object, and then check off the correct box to tell whether it is a light source or not.
Use this simple and colourful worksheet to teach your kids more about light and sound, and some common sources of light and sound. In this assessment, your little ones will be introduced to some objects that can create light, and also some objects that create sound. Ask them to identify the objects in this colourful printout, and then help them check off if the object is a light source, a sound source, or both.
Just as we use sounds to communicate effectively, we can also use lights to signify what we mean and what we want others to do. In fact, light can be used in many different ways. Before starting this exercise with your kids, ask them if they can give you some examples of light used as a means of effective communication. Then, help them check off the pictures of light sources being used to communicate in the worksheet.
There are so many things to do at the park, and your students probably enjoy spending time there. Before completing this worksheet, get your students ready for the exercise by asking them to recall some of the things they often see and love to do at the park. Now, ask them to identify the things in the picture, find all the objects that make sounds, and check the correct answers.
Safety is something very important that your kids have to be made aware of as soon as possible. There are many things that we can do and rules to follow to ensure our safety and the safety of other people. It is important that your let your kids know what sounds they need to react to once they hear it. Look at the pictures in the worksheet and help your kids identify the objects. Then, ask them to identify which of the objects produce safety sounds to warn us that we must watch out, and check the correct answers.
Sounds are everywhere around us. We make sounds when we talk, animals make sounds, objects around us make sounds, and even the wind makes sounds sometimes. You can ask your students if they can recall some objects that make sounds. Then, help them check the pictures in this worksheet that are sources of sound.
Sounds are an important part of communication; with the help of sounds more information can be communicated effectively. Ask your students if they can tell you some of the sounds that people, animals, and things make to communicate. Then, look through this worksheet with them. Ask them if they can identify the activities going on. Then, ask them to circle examples of using sound to communicate in this colorful worksheet.
When light is cast on some objects, it forms a shadow. Your students are probably familiar with their shadow. Use this worksheet to teach them more about how shadows are formed. Some objects block light and create a shadow. Other objects do not block the light, so they do not create a shadow. Help your students check off the boxes next to the pictures that would create a shadow in this educative printout.
